ROD AND BOLT CUTTER.

:SPECIFICATION forming part of Letters Patent No. 326,772, dated September 22,] 885.

Application filed Ntvember 18, 1884. (No model To all whom it may concern.-

Be it known that 1, DAVID R. NICHOLS, a citizen of the United States, residing at Brockville, Province of Ontario, and Dominion of Canada, have invented certain new and useful Improvements in Rod and Bolt Gutters and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and is a side view. .Fig. 2

is a View of the reverse side, a section being taken through the cam of the movable lever. Fig. 3 is a horizontal section.

This invention has relation to bolt-cutters and it consists in the construction and novel arrangements of devices, as hereinafter set forth, and poiniel out in the appended claim.

In the accompanying drawings, the letter A designates that branch of the cutter which carries the stationary bit 13, which is secured by a set-screw in a recess, 0, in the end of the arm D, which extends upward from the pivot e, which connects the branch A to the other branch, F, of the instrument. The branch A is also provided in its inner face with a recess, 9, having a marginal wall, a, which extends around the broad pivotal portion 70 in circular form, while its end portions, 1, become gradually parallel as they approach the bit'seat c. The guide portions Z of the margin are made positively parallel only at their upper ends, their lower portions diverging to allow play to the lower or movable bit, E, and its holder G. The holder G is recessed at m to receive the bit E, which is secured therein by a setscrew, a, which passes through a spline in the back ofthe hollow, indicated at b. This spline engages a guide-slot, (Z, in the back of the branch A, and moves with the holder therein as said hollow is operated by the lever-branch F. The lower inner end of the holder G is provided with a circular bearing, H, which engages the circular eccentric V on the inner face of the broad portion P of said leverbranch. The pivotbar z of said branch is received in the center bearing, 12, of the main branch A, and the bolts connects the branches together in proper relative position. An opening, I, is made in the main-branch, through which the bolt or bar to be cut extends.

In its operation this cutter is very effective. In addition to the powerful eccentric action which forces the movable bit outward, this bit is given a lateral-drawing motion, so that the action is easier and the cut a cleaner one than if the movable bit should operate by a parallel movement of all points of its cuttingedge.

Having described this invention, what I elaim, and desire to secure by Letters Patent, 1s

The improved bolt-cutter, consisting of the two branches A and F, the branch A having the fixed cutter B and provided with the bithollow having diverging guide-walls, a guideslot, (1, the pivot aperture and the opposite branch F, with the eccentric V, the pivot-bar Z, and the movable bit-holder G, arranged in the said hollow, and provided with the circular aperture to be engaged by the eccentric, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID RICHARDSON NICHOLS.
